MatteEnabledComponent

public MatteEnabledComponent()

Method Detail

setMatte

public void setMatte(Matte matte)
              throws MatteException

Adds an Matte to this component in order to enable matte compositing. If there is already a Matte assigned to the component, and this Matte is animated, it has to be stopped before any call to this method.

Specified by:

setMatte in interface MatteEnabled

Parameters:

matte - the Matte to be assigned to the component. At any point of time there can only be one matte associated to the component, that's way any matte that has been associated before will be overriden by a call to this method. The Matte parameter can also be null, in this case there is no matte associated with the component after the call, even if there had been one before.

Throws:

MatteException - if the Matte has an unsupported type, the platform does not support mattes at all, or an animated matte is associated with the component and is still running

getMatte(), Matte

getMatte

public Matte getMatte()

Return the Matte currently associated with the component.

Specified by:

getMatte in interface MatteEnabled

Returns:

isDoubleBuffered

public boolean isDoubleBuffered()

Returns true if double buffering is available and activated.

Returns:

true if double buffering is available and activated, and false otherwise

isOpaque

public boolean isOpaque()

Returns true if the whole area of the Component (as returned by the com.sun.lwuit.Component#getBounds method, is opaque.

Returns:

true if all the pixels within the area defined by the com.sun.lwuit.Component#getBounds method are opaque, i.e. all pixels are painted in an opaque color, false otherwise.

processEvent

protected void processEvent(AWTEvent event)

Handle the specified AWTEvent.

Parameters:

event - a java.awt.AWTEvent to handle.
